A good regulator setup is something like this setup that gives you dual gauges, solenoid, bubble counter and needle valve. The newer regulators come preset to give you around 15-20psi of back pressure to the needle valve. All you would need to adjust is the needle valve around 3-4 bubble per second. If you get a older regulator they work too. You just have to dial in the main diaphragm to 15-20 psi to keep back pressure on it to the needle valve. Any psi lower than that will cause the regulator diaphragm to stick. (I speak from experience).

The regulators to stay away from would be beer tap regulators. They will not give you the easiest control you would want with starting out. See photo below for example.
